We broke up. what are his next moves going to be?

He's just trying to make you feel guilty, you soo did the right thing in dumping him, he's not worth your time. Let him go and move one. His next moves are gonna be like commenting on girls pics on FB, and try to seem happy in front of you. Hes lying, trust me. What you need to do is delete him of FB. Im sure you can find something wayyy better, keep your head up high ;)
